B56 & B57 SERIES MOUNTING
NOTES:
1. Minimum hood distance above cooktop must not be less than 30”.
A maximum of 36” above the cooktop is highly recommended for best capture of cooking impurities.
Distances over 36” above the cooktop are at the installer’s and user’s discretion - providing that ceiling height and flue length permit.
8¼”
MAX.
1. GROUNDING INSTRUCTIONS
This appliance must be grounded. In the event of an electrical short circuit, grounding
reduces the risk of electric shock by providing an escape wire for the electric current. This
appliance is equipped with a cord having a grounding wire with a grounding plug. The plug
must be plugged into an outlet that is properly installed and grounded.
2. Position the electrical outlet within the space covered by the decorative flue and
where it will not interfere with the round duct. Make sure the outlet is no further
than 8¼” from where the cord exits from the hood and that the outlet does not
interfere with a mounting bracket fastening area or where the decorative flue touches the wall.

1. Construct wood wall framing that is flush with interior surface of wall studs.
Make sure:
a) the framing is centered over installation location.
b) the height of the framing will allow the mounting bracket
to be secured to the framing within the dimensions
shown.
2. After wall surface is finished, carefully center and level the hood
mounting bracket and secure it to wall framing with (3) #8 x 1-1/2”
mounting screws. Tighten the screws completely.

Minimum 30”, Maximum 36” (for ducted discharge)
Minimum 30”, Maximum 33” (for non-ducted discharge)
